Only position the jack on the jack support points
intended for this purpose. You could otherwise
damage the vehicle.
Important notes on using the jack:
Only use the vehicle-specific jack that has
R
been tested and approved by Mercedes-Benz
to raise the vehicle. If the jack is used incor‐
rectly, it could tip over while the vehicle is
raised.
The jack is designed only to raise the vehicle
R
for a short time while a wheel is being
changed and is not suitable for carrying out
maintenance work under the vehicle.
Avoid changing a wheel on uphill and downhill
R
slopes.
The jack must be placed on a firm, flat and
R
non-slip surface. If necessary, use a large,
flat, load bearing and non-slip underlay.
The base of the jack is positioned vertically
R
under the jack support point.
Safety instructions while the vehicle is raised:
Do not put your hands or feet under the vehi‐
R
cle.
Do not lie underneath the vehicle.
R
Do not start the engine and do not release
R
the parking brake.
Do not open or close any doors.

Jack support points
Only use the middle rod and the pump lever rod
with the largest diameter for the jack as a lug
wrench extension. Only insert the middle rod on
the lug wrench, and always as far as it will go.
Otherwise, the rods could bend and deform so
much that they can no longer be used as pump
levers for the jack.
To prepare the hydraulic jack: insert the
#
third rod of pump lever
the lug wrench extension.
Close pressure release screw 3.
#
To do this, use the flattened section on pump
#
lever
1
to turn pressure release screw
clockwise to the stop.
%
Do not turn pressure release screw
than one or two full turns. Hydraulic fluid
could otherwise escape.
Insert pump lever

#
the recess on the jack and secure by turning
it clockwise.
